To all whom it may concem:

Be it known that I, WILLIAM W. PAR- MENTER, a citizen of the United States of America, residing at Redford, in the county of Wayne, and State of Michigan,- has invented certain new and useful Improvements in Power-Frames, of which the following is a' specification, reference being had therein to the accompanying drawing.

This invention relates to a power frame and has for its object the production of a simple and eflicient power frame which is adapted to be used in connection with automobiles or other motor vehicles whereby 1plower may be obtained and transmitted om the rear drive wheels of the motor ve hicle.

Another object of this invention is the production of a simple and efiicient power frame which is light in construction and upon which may be easily and efliciently attached a saw frame or other machine which is adapted to be driven from the drive wheels of a motor vehicle.

With these and other objects in view, this invention consists of certain novel construc tions, combinations and arrangement of parts as will be hereinafter fully described and claimed.

In the drawings:

Fi re 1 is a side elevation of the power attac ment shown coiiperating with the drive wheels of a motor vehicle.

Fig. 2 is a central, longitudinal section of the power frame shown connected to an automobile, the drive axle thereof being shown in section.

Fig. 3 is aside elevation of an automobile,

Fig. 4.

ig. 7 is a fragmentary sectional view taken on line 77 of Fi 4. Fig. 8 is a section ta on on line 8-8 of Fi 4. Fig. 9 is a detail fragmentary, perspective 66 view of one corner of the power frame.

Fig. 10 is a detail perspective'of one corner of the machme frame which is adapted to rest upon an ob ect supported by the power frame By referring to the drawings'it will be seen that'l designates the frame of the automobile which is provided with the usual rear drive axle 2. This axle 2 supports the usual rear drive wheels 3.

A power frame is adapted to cooperate w1 th the rear axle 2 of the automobile 1 and the frame comprises a part of bottom runners 4 The runners are of channel iron construct1on and are rovided with upwardly curved forward en s 5 as shown clearly in Flgs. 2 and 3.

These runners 4 are adapted to be arranged in spaced, parallel relations, and each runner carries a strap plate 6 upon the top edge thereof as shown clearly in Fig. 6 of the drawings. These strap plates 6 are provided with upwardly inclined forward ends 7 which forward ends are provided with cradle-sockets 8. The extremity of these cradle-sockets 8 overhanging the ends 5 as shown in Fig. 7 and being riveted or otherwise permanently secured to the upper ends of the upturned ends 5. Suitable rivets 9 are employed for firmly holding thereby plates 6 in engagement with the channel irons 4.

An end angle plate 10 is secured to the rear ends of the strap plates 6 by means of the bolts 11 which pass therethrough and which also extend through the channel runners 4. A transversely extending angle plate 12 is secured to the top of the plates 6 and faces angle plate 10 as shown clearly in Figs. 4.and 5 of the drawings, the angle iron 12 is braced by means of the angle braces 13 which engage the rear of the angle plate 12.

A power shaft supporting bracket 14 is carried by the upwardly inclined end 7 of each plate 6 and these brackets 14 support a power shaft 15. Each bracket 14 is provided with laterally extending feet 16 which feet are provided with elongated apertures 17 for receiving securing bolts 18 carried by the ends 7 It should be understood that these brackets 14 may be adjusted to a proper position for holding'the friction wheels 19 in proper en agement with the tires of the wheels 3. ese friction wheels 19 are carried on the shaft 15 and are adapted to fric- 23 formed in one b. plates 21. These plates the angle plates 10 and 12.

tionally engage the wheels 3 whereby powermay be transmitted through said w eels 19 to the shaft 15 from the wheels 3.

The machine frame 20 is supported upon the ower frame and may be of any suitable or esired construction without departing from the spirit of the invention. This machine frame 20 is provided-with a plurality of converging, supporting legs which sup- .porting legs are braced at their lower ends means of the a hold the frame 20 against lateral shifting vtion wheels 19 may movement.

The frame 20 is provided with a suitable table 25 and a shaft 26 is supported upon the top 20 as shown in Fig. 2 of the drawing. This shaft 26 is adapted to support a saw 27 as shown in Fig. 1, and a drive pul' ley 28 is also carried by this shaft 26, a

suitable drive belt passes over the pulley 28 and also passes over one of the pulleys 30 formed upon one of the friction wheels 19.

When it is desired to operate the saw or other machine mechanism which may be substituted for the saw, a-power frame 1s placed in the position such as 1s illustrated in Fig. 3 of the drawings in order that the cradle-portion 8 may fit under the axle 2. After the frame has been placed or forced into the position shown in Fig. 3, the outer end of the power frame may be forced downwardly thereby moving and liftin the axle 2 upwardly and relieving the w eels from the ground, this movement is ossibly due to the rocking action and everage whichis obtained by the power frame when forcing the same downwardly. The fricbe adjusted into frictional engagement with the wheels 3, and by attachin the the ower 'me as above described, and placing the belt 29 over the pulleys 28 and 30, power may be transmitted from the drive wheels of the motor vehicle to the shaft 26.

I claim:
